Dear sir,
I want to use Opencv4.3.0 in TDA4VM(A72, Qnx), but got error as below:
This Opencv build doesn’t support current CPU/HW configuration
Required baseline features: NEON not AVAIABLE.
As we all know, A72 support NEON,and I wrote some code with NEON instructions, it also ran as well .
The opencv is downloaded from QNX websites.
Would you please tell me what's wrong with it?

Hi,
The TI Processor SDK for QNX release does not test OpenCV, as such QNX / Blackberry is a better contact for support on this issue, to ascertain what the error is reporting.
As per the TDA4V TRM, the ARM Corext-A72 Subsystem on the A72 supports "Advanced Single Instruction Multiple Data (SIMD) and floating point extension (Arm Neon
)".
Please refer to this page that points to the ARM Architecture Reference Manual that gives full instruction set details. Notes on using GCC with Neon, are at ARM NEON Intrinsics - Using the GNU Compiler Collection (GCC)
